Large volume holographic imaging for biological sample analysis

Volume holographic hyperspectral imaging.

A volume hologram has two degenerate Bragg-phase-matching dimensions and provides the capability of volume holographic imaging. We demonstrate two volume holographic imaging architectures and investigate their imaging resolution, aberration, and sensitivity. The first architecture uses the hologram directly as an objective imaging element where strong aberration is observed and confirmed by sim...

Volume holographic spectral imaging

We report on a volume holographic imaging spectrometer (VHIS) system which allows retrieval of a scene's twodimensional spatial information as well as its spectral information. This is performed using a transmission volume hologram and a simple rotary scanning mechanism. The system has the advantages of high spectral and spatial resolutions and the potential of single-shot, four-dimensional (3D...

Analysis and Optimization for Volume Holographic Recording

Information content of volume holographic imaging.

We discuss the general properties of optical imaging in three-dimensional object domains from an information-theoretic standpoint, expressing system performance in terms of imaging mutual information (IMI). We use IMI to characterize volume holographic imaging, a new optical imaging method with depth discrimination capability. The performance of this holographic method in imaging a simple discr...

Biological imaging by Digital Holographic Adaptive Optics

The basic principles of DHAO have been presented and demonstrated in a recent paper [Opt. Lett. 36, 27102712(2011)]. In this paper, the application of DHAO in biological imaging is investigated. OCIS codes: 090.1995; 110.1080
